Femoral data are based on 5 mice at baseline (3 weeks of age), 10 mice at 5 and 12 months and 15 mice at 18 months in each diet group. Vertebral data are based on 6 mice at 12 months in each diet group and 6 mice in each of the two high-fat diets at 18 months. Values are means and standard deviations. Statistical significance was determined by ANOVA followed by paired group comparisons. “*” are placed to show the statistically significant drop in the BMD relative to baseline. “a” and “b” are placed on the HFWD+minerals group: “a” shows statistically significant increase relative to the HFWD group, “b” shows statistically significant increase relative to control; “c” is placed on the control+minerals group, and shows significant increase relative to the control (p <0.05). Data from baseline and 5 months in all groups and in control diets at 18 months for the vertebrae are not available.
